Abstract

The invention discloses a feed additive capable of preventing and treating a chronic aleutian disease of minks and a preparation method of the feed additive. The feed additive is prepared from the following components of enteromorpha, seeds of coral peatree, black sesame seeds, kelp, clamworm powder, fish scales, olive oil, herb of sibirica walking fern, radix rubiae, roots of snow of June, kochia scoparia seedlings, largehead atractylodes rhizomes, corn stigma, fennel fruits, radix linderae, bauhinia variegate roots, bark, leaves and flowers, pummelo seeds, russula virescens, roots or stem of smoothfruit ventilago, roots of silverweed cinquefoil, radix curcumae, ginseng, radix polygoni multiflori and licorice roots. The feed additive disclosed by the invention does not contain antibiotics, is non-toxic and harmless to the minks, and is convenient to use; medicines can exert effects quickly, the feed additive has a good treatment effect on the minks suffering from the chronic aleutian disease, the immunity of the minks is strengthened, and increase of economic benefits of breeding households is facilitated.

Description

technical field [0001] The invention relates to a feed additive, in particular to a feed additive for preventing and treating mink chronic Aleutian disease, and also relates to a preparation method of the feed additive. Background technique [0002] Mink fur is a kind of precious fur, which has various varieties and colors, and is expensive. It has the laudatory title of "King of Fur". Judging from the quality and value of mink fur, its utilization rate is also higher than that of large capillary fur such as fox and raccoon fur, especially in the domestic market with great potential. Mink fur is famous for its short plush, bright and luxurious. It is the main raw material skin for making clothes, collars, hats, cuffs and decorations. It is widely used and in great demand. Fox and raccoon fur and other large capillary fur are thicker and longer than mink fur, but not as gorgeous as mink fur. The domestic market is not suitable for making coats, but only for collars, cuffs, s...

Problems solved by technology

[0007] 2. The effect on the reproductive performance of mink. The disease can cause the female mink to have no heat, empty pregnancy, miscarriage, stillborn fetus, weak fetus; the male mink's breeding ability and sperm motility are reduced, causing serious and invisible economic losses to the breeding unit.

[0009] At present, there is no effective vaccine for Aleutian disease, and there is no specific therapy for this disease. Treatment with the immunosuppressant cyclophosphamide can control the appearance of Aleutian disease within a certain period of time, but it cannot be completely cured. The degree of disease also has a certain resistance to it, and the treatment effect is even worse

Therefore, the current reliable method is to eliminate sick minks and purify mink farms through multiple specific quarantines, which will cause great economic losses to the farms
